Bert, I'm not familiar with these glues and don't know what "Gorilla Glue" refers to. I am familiar with some automotive adhesives, and one is affectionately called "gorilla snot". It's proper name is trim adhesive, and it's typically yellow and viscous, hence the nickname. If by chance this is what you are referring to, I'd be very leery about using it on an instrument without feeling I had solid information from a reliable source.
